[Explain what a combobox is.]
While Tk doesn't build in a combobox widget [will this change in 8.4?], there's a wealth of implementations available. Bryan Oakley's is pure-Tcl, widely used, and maintained efficiently. BWidgets is a popular pure-Tcl widget set [in Batteries Included distributions?] with an excellent combobox. [... List others, including Donal Fellows', the Iwidgets one, ...]
[Point to the docs to these various comboboxs!!!]

widgets and megawidgets, including ComboBox, Motif style FileSelectBox, MS
Windows style FileSelectBox, PanedWindow, NoteBook, Hierarchical
Listbox, Directory List/Tree View, Spin Control widget, Balloon help
window and many more. Tix also has built-in support for XPM
images. A Form geometry manager makes it easy to lay-out your
interface using Motif Form-like attachment rules.
Tix 4.x is written in C, and requires building a new
interpreter based on Tk 4.0/Tcl 7.4 or newer.
It can also be used with itcl 2.0 or newer.
Tix 4.x now works with Embedded Tk as well.
Tix 4.x works on both Windows and Unix platforms.
Tix 4.x has license terms similar to the Tcl/Tk license terms.
The tixbindings file is some additional bindings for the TixHlist
widget, including scrolling, entry editing, and local drag and
drop. Version 4.1 works with Tk 8.0.
Mumit Khan has, at the xraylith site, a simple patch for Tix
to get the demos to work under Tk 8.0 patched with Img 1.1's
Tcl object support.
The Tix widget set has been adopted by Gregg Squires at the
mne web site.
The ncnr patches to Tix allowed creator to compile Tix 4.1 with
Tcl/Tk 8.2.3 on a SGI.
The infinit site has a Windows implementation (version 4.1.8.2),
using stubs, as well as a variety of patches.
The two sourceforge sites provide NetCVS access to two different
Tix source code trees. One is designed for stability and cross
platform interests, while the other is designed around new design
decisions and development.
The current version of Tix is 8.1.1, with an beta release of
8.2.0 available for testing.

Try this one: http://incrtcl.sourceforge.net/iwidgets/iwidgets/combobox.html
In Enhancing BWidget is demonstrated how to extend the behavior of BWidgets' comboboxes, to add a history of previous input; or to make them look like a chooser (somehow like the tk_optionMenu (which also is a kind of combo, but looks kind of old-fashioned these days). RS
